Aim of the study.:
To evaluate the practice of minimally invasive restorations, their survival failure rates, the possible biological and technical complications and the impact of various factors on the prognosis of these prostheses.

This is a cross-sectional study carried out on a representative sample of 77 clinical cases, treated in the department of fixed prosthodontics and at private dental offices. A statistical analysis and a comparison between the obtained results with those of studies in other countries were carried out.

The overall survival rate of minimally invasive restorations was 87.5%, the incidence of this rate differs according to the age of the restoration: after 3 years (95%), after 5 years (81.2%) and after more than 5 years (83.3%). Dental veneers present half of the restorations studied with a survival rate of 82% . On the other hand, the posterior restorations have a 100% survival rate. Glass-ceramics are the most used, followed by hybrid ceramics with a percentage of 71.4% and 19.5%, respectively. The most common failures are debonding (18.2%) and total fracture (10.4%).

The survival or failure rate of minimally invasive restorations is influenced by several factors: the type of prosthesis, the material used, the type of adhesive system and the restoration sector. Indeed, it is necessary to carry out a detailed clinical examination to guarantee the durability of the prosthesis and to analyse the mechanical and optical properties of the various ceramic materials. It is also important to respect the operating protocol and to ensure the clinical follow-up of the patient.
